LIGHTING DEVICE FOR CLEAN ROOM

摘要

The device has a bonnet (3) provided parallel to a support plate (2). Electroluminescent diodes (5) are provided as a light source. The support plate places the electroluminescent diodes in a position. The support plate and the bonnet form an envelope structure for closing the device. The envelope structure provides two principal external opposite faces. Side walls (31) connect the principal faces by forming an obtuse angle with an extension virtual plane, where the obtuse angle is ranged between 115 and 160 degrees. The bonnet is made of plastic, glass, aluminum and/or incorporating steel of optics transparency. The device is made of a polymeric coating material i.e. polyurethane.
